Smart nodes for providing interoperability among a plurality of web services in a chain and dynamically orchestrating associated processes

ABSTRACT

A smart node is integrated with each Web service in a Web service application chain to automatically supply compatible features, missing functionality, and orchestration of the processes in the application, without coordination by an orchestration engine, in an embodiment. A smart node is a software program that systematically specifies the communications dimensions, functionality, and orchestration required for interoperability among Web services. The communications parameters, backup functionality, and process orchestration required for the Web services in a Web service application may be predetermined and programmed into smart nodes. The smart nodes are subsequently integrated with the Web services in a Web service application so that communications among the Web services occur first through the smart nodes. The smart nodes can thus supply communications parameters, any missing functionality, and dynamic process orchestration based on the current event context of the Web service application. A smart node further enables a Web service to supply different functionality in different contexts.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of PPA Ser. No. 60/590,745, filed Jul. 23, 2004 by the present inventors.

FIELD OF THE INVENTION

This innovation relates to services, and, more particularly, to methods that supply the communication parameters and functionality required for invoking services.

BACKGROUND OF THE INVENTION

Services are software services that are annotated with additional information to provide a useful abstraction for a business purpose. A service is a discrete piece of logic with a defined set of capabilities for input and output. The following are examples of services:

-   -   Java programs,     -   Portlets, and     -   Web services.         Web Services

The promise of the Internet is an open e-business platform where companies can do business spontaneously with anyone, anywhere, and anytime without requiring that companies abandon their existing software applications and infrastructures. Increasingly companies rely on the Internet to obtain loosely coupled Web services deployed by Web service providers on application-based servers, which are computers on networks that manage the networks.

Web services are business-enterprise computer applications that can be utilized singly or collectively to accomplish a wide range of intended purposes, such as determining health-care patients' eligibility for benefits, submitting health-care claims, and providing stock quotes. Web services help companies dramatically cut costs, increase revenues, and improve competitive agility by combining existing, heterogeneous systems into cross-functional, multi-company applications. For example, Web services designed for insurance companies help them rapidly automate their business processes, eliminating paper and manual touches and saving them tens of millions of dollars annually. To supply such valuable and widely needed services, Web services providers may offer multiple Web services to client businesses.

Because Web services can operate independently of a particular computer language, platform, or location, a client business and a Web service may each use different computer languages, platforms, and locations in widely distributed systems over one or more networks.

Open Web service standards have been developed for compatibility among Web service applications. A standard called SOAP (Simple Object Access Protocol) has been developed to define the format of messages exchanged among applications. The content of messages, such as a request for an action to be performed by a Web service, is currently described in WSDL (Web Services Description Language), which is an XML (Extensible Markup Language)-formatted language and which serves as a Web service's interface. Web services are cataloged in a Web based directory and infrastructure called UDDI (Universal Description, Discover and Integration), which is an Internet registry where businesses list themselves according to their services. Communications between a client business and a Web service further rely on the use of a shared transport protocol, such as HTTP (Hypertext Transport Protocol), which enables communications over the Internet.

Typically a client business employs a client application to communicate from its Web site over the Internet according to these standards, to obtain the Web services offered by a Web service provider from its server-based Web site. The Web service provide uses the same standards to reply to a client. Other known or not-yet-known Web service protocols and standards may be used for this communications.

The Web service end point is the physical location of the Web service on a sever and implements the Web service interface.

Web Services Applications

Web services applications are computer applications that use Web services singly or collectively to accomplish intended purposes. To work with a specific Web services application, a Web service needs accept business documents, process them, and pass them on in ways compatible with the Web service application.

A Web service application typically consists of one or more Web services, a document that describes how those Web services are to be used, Web portal pages, and UDDI entries.

FIG. 1 shows an example of how multiple chained Web services are typically used as part of a Web service application for the filing and payment of medical insurance claims. Chained Web services are loosely connected Web services that may reside on different servers and that may be provided by separate businesses. A Web service provider employs a server 100 running a Web portal page 200 and a Web service application 300.

A Web portal page 200 is a Web site interface that a person can reach over the Internet. Web site interfaces are computer-programmed modules that allow end-users to select variables and parameters from easy-to-use visual displays or to type in this input, save the information through selecting a save option, and have their selections automatically applied by computer subsequently, without those users having to program the information manually.

In this example, an attendant at a clinic computer 150 can use the Internet, through a wired link 144, a telephone network 130, and another wired link 142, to reach the portal Web page 200 on the Web service provider server 100. The attendant can then use the portal Web page 200 to fill out a claim file form 220 for one of the clinic's patients and submit it to Web service application 1 300.

Other means for submitting claims also exist. For example, an attendant at a clinic computer 150 might use link 144, network 130, and link 142 for a machine-to-machine transmission of a claim file directly to Web service application 1 300. Many kinds of wired and unwired links and networks could used for this machine-to-machine transmission, such as the Internet, a private LAN (Local Area Network), a wireless network, a TCP/IP (Transmission Control Protocol/Internet Protocol) network, or other communications system.

To continue with the example, Web service application 1 300 receives each claim file through Web service 1 410, which relays the data back over link 142, network 139, and link 143 to server 2 182. If necessary, Web service 2 420 transforms the format of the claim file to a format that Web service application 1 300 can use for its full operations. For example, a claim file might have been sent in NSF (National Standard Format) format, but Web service application 1 300 might require HIPAA (Health Insurance Portability and Accountability Act) format.

After the claim file is transformed to the correct message format, Web service 2 420 relays the data back over link 142, network 139, and link 145 to Web service 3 430, which is used to validate the claim file. In turn, Web service 3 430 relays the data back over link 142, network 139, and link 147 to Web service 4 440 is used to send the claim file back over link 142, network 130, and link 148 to an insurance company server 170 for payment to the clinic.

For Web service application 1 300 to carry out its operations successfully, the chained Web services 410, 420, 430, and 440 must be compatible and functional. However, when Web services 410, 420, 430, and 440 are on the servers of different Web service providers, they may not have been set up with compatible communication dimensions, which can make interoperability among them impossible. Moreover, if one Web service is dysfunctional, the chain may be broken and the operations blocked.

For example, the following list shows typical examples of communications dimensions that may require compatibility:

-   -   Response time settings     -   Error rate settings     -   Message formats, such as SOAP flavors or NSF or HIPAA formats     -   Security features, such as username and password     -   Management features, such as the clients service level and         software versions.     -   Routing information through the chain of Web services

Furthermore, if Web service 2 420 is dysfunctional at a particular time, because of a power failure, for example, Web service application 1 410 cannot complete its operations. In such a case, to follow the example in FIG. 1, patients' claims could not be submitted to a payer.

For these reasons, methods are needed that can ensure compatibility among chained Web services and that can substitute functionality from other similar Web servers in the chain when one Web service is down.

Prior Techniques

Typically programmers must manually program substantial portions of the Web services chained in an application to ensure compatibility and functionality in spite of Web service breakdowns.

For example, FIG. 1A shows an operating environment where multiple chained Web services 420, 430, and 440 on separate servers 182, 184, and 186 are used in conjunction for a client computer 150 through an orchestration engine 300 programmed on an additional server 100. The orchestration engine 300 serves as a broker to arrange for the proper use of the different Web services 420, 430, and 440 in appropriate ways and at appropriate times.

However, manual programming is time-consuming and requires special and expensive programming skill, which makes it expensive. Furthermore, a pre-programmed orchestration engine on a separate server is an additional expense and may not provide adequate flexibility for the many conceivable steps required for the successful orchestration of multiple Web services.

Therefore there is a need for a method and apparatus that provides a more automatic method for ensuring compatibility among chained Web services and for replacing the operations of a dysfunctional Web service in the chain.

BRIEF SUMMARY OF THE INVENTION

These and other needs are addressed by the present invention. The following explanation describes the present invention by way of example and not by way of limitation.

It is an aspect of the present invention to provide an automatic method for successfully chaining Web services in a Web service application.

It is another aspect of the present invention to provide an automatic method for ensuring compatibility of features among chained Web services without coordination by an orchestration engine.

It is another aspect of the present invention to provide an automatic method for replacing the functionality of a dysfunctional Web service in a chain with the functionality of another Web service in the chain without coordination by an orchestration engine.

It is another aspect of the present invention to provide an automatic method for placing data in a queue until a dysfunctional Web service in a chain becomes functional again.

It is an aspect of the present invention to provide an automatic method for successfully chaining Web services in a Web service application through dynamic, context-driven orchestration.

DETAILED DESCRIPTION

The following description explains a method and apparatus to supply a smart node to each Web service in a Web service application chain to automatically supply compatible features and to replace any missing functionality. The details of this explanation are offered to illustrate the present invention clearly. However, it will be apparent to those skilled in the art that the concepts of present invention are not limited to these specific details. Commonly known elements are also shown in block diagrams for clarity, as examples and not as limitations of the present invention.

Operating Environment

An embodiment of an operating environment of the present invention is shown in FIG. 2. A party employs a server 100 to run a Web service application 300, which uses multiple chained Web services 410, 420, 430, 440 located on multiple serves 100, 182, 184, and 186. The servers 100 may be personal computers or larger computerized systems.

The Web services 410, 420, 430, 440 communicate through a wired or wireless network 130 and wired or wireless links 142, 143, 145, 147, and 148. The network 130 may be the Internet, a private LAN (Local Area Network), a wireless network, a TCP/IP (Transmission Control Protocol/Internet Protocol) network, or other communications system, and may comprise multiple elements such as gateways, routers, and switches. The links 142, 143, 145, 147, and 148 are compatible with the technology used for network 130.

Smart Nodes

The programmer or programmers who design Web service application 1 300 create smart nodes 302, 304, 306, and 308 for each Web service 410, 420, 430, 440 in the chain orchestrated by Web service application 1 300. A smart node is a software program that systematically

-   -   Specifies the communications dimensions and functionality         required for interoperability among chained Web services 410,         420, 430, 440;     -   Provides for replacement of missing functionality; and     -   Orchestrates the processes of the application dynamically, based         on the current event context of the Web service application.

In a sense, a smart node is itself a Web service that defines the formal aspect that other Web services require to be able to work together in a chain. Because of the systematic way that a smart node presents this information, any further required programming is simplified.

Unlike in the orchestration engine system described above, the smart nodes 302, 304, 306, and 308 in the present system are programmed to operate independently and in a distributed fashion to dynamically supply communications dimensions and functionality based on the context of the Web service application that invokes them. Through the present invention, a smart node further enables a Web service to supply different functionality in different contexts. A Web service with such a smart node can be a member of multiple Web service applications, with the smart node supplying the different communications dimensions and functionality required by each Web service application.

For example, in an embodiment a smart node 2 182 could be programmed to encrypt the credit card numbers for the patients referred to by a first Web service application, which requires such security, but not for patients referred to by a second Web service application, which does not share this security requirement. Alternately, the smart node 2 182 could be programmed to encrypt the credit card number of one specific patient or customer but not that of another specific individual.

In this embodiment, communications among chained Web services 410, 420, 430, 440 take place first through smart nodes 302, 304, 306, and 308 so that each smart node can specify the required communications dimensions to the Web service with which it is integrated, meaning programmed to work with, and can further ensure required functionality.

Alternate Embodiments

In another embodiment, a smart node 302 can be designed for a Web service application 1 300 that employs only one Web service 410. In this case, the smart node 302 specifies the communications dimensions Web service 410 needs to use to be compatible with Web service application 1 300. In yet another embodiment, service application 1 300 could employ a single Web service 430 on another server 184 and smart node 306.

In another embodiment, Web services 410, 420, 430, 440 can all be located on one server 100.

In still another embodiment, shown in FIG. 2A, a smart node 312 may be located on a client computer 170 along with a Web service application 330 that employs Web services 420 and 430 on a remote server 182. In this scenario, smart node 312 supplies the communications dimensions and missing functionality for Web services 420 and 430.

Examples of Smart Node Communications Dimensions

In an embodiment, smart nodes 302, 304, 306, and 308 might usefully specify parameters for the following communications dimensions for the Web services 410, 420, 430, 440 chained through Web service application 1 300. In different embodiments, smart nodes 302, 304, 306, and 308 might apply these dimensions uniformly to all the Web services 410, 420, 430, 440 in the chain or might supply different dimensions for individual Web services within the chain.

-   -   Performance         -   This category might specify which response-time setting             should be used (for example, 10 seconds or 20 seconds). It             might also specify the error-rate percentage that should be             used (for example, less than 1%).     -   Interoperability         -   This might specify what formats the Web services 410, 420,             430, 440 must follow to be compatible with Web service             application 1 300. For example, it might specify the message             formats to be used, such as particular SOAP flavors or NSF             or HIPAA formats.     -   Security Features         -   These might indicate the username, password, and type of             encryption to be used.     -   Management Features         -   These might specify the business service level and software             versions to be used.     -   Routing information         -   This might specify the pre-processing and post processing of             each Web service in the Web service application, in other             words the choreography of which Web service is used at each             step of the process governed by Web service application 1             300.     -   Reliability         -   This might guarantee delivery of a message. For example if             Web service 4 440 is down, smart node 3 306 might be             programmed to replace the functionality of Web service 4             440. Or smart node 3 306 might place its data in a queue             until Web service 4 440 is functional.             Examples of Functionality

The smart nodes 302, 304, 306, and 308 supply the functionality required for all the Web services 410, 420, 430, 440 to operate successfully that are chained through Web service application 300.

For example, in an embodiment smart nodes 302, 304, 306, and 308 arrange for the replacement of the following functionality among any of the web services 410, 420, 430, 440 shown in FIG. 1:

-   -   Receive claim file     -   Transform message format     -   Validate claim file     -   Send file to payer

Alternatively, the smart nodes 302, 304, 306, and 308 shown in FIG. 2 could specify that when a Web service, such as 430, is dysfunctional the data sent to the Web service 430 would be placed in a queue until the Web service 430 becomes functional again.

Process of Supplying Smart Nodes—Overview

FIG. 3 is top-level flow chart that illustrates a process for a Web service provider to automatically supply the smart nodes, through the operating environment shown in FIG. 2. It will be useful to explain the steps in this process briefly from a high level and then to expand elements of this explanation in detail.

Step 1000 in FIG. 3. Determine communication dimensions required for chained Web services 410, 420, 430, & 440.

A programmer or programmers determines the communication dimensions required for the Web services 410, 420, 430, & 440 chained for use with a Web service application 300.

Step 2000 in FIG. 3. Determine backup functionality required for chained Web services 410, 420, 430, & 440, shown in FIG. 2.

A programmer or programmers determines backup functionality required for the Web services 410, 420, 430, & 440, shown in FIG. 2, chained for use with a Web service application 300.

Step 3000 in FIG. 3. Create smart nodes for required communication dimensions and backup functionality.

A programmer or programmers creates the smart nodes 302, 304, 306, and 308, shown in FIG. 2, for the Web services 410, 420, 430, & 440 chained for use with a Web service application 300.

Step 4000 in FIG. 3. Integrate smart nodes 302, 304, 306, and 308 and the chained Web services 410, 420, 430, & 440.

A programmer or programmers integrates the smart nodes 302, 304, 306, and 308, shown in FIG. 2, and the Web services 410, 420, 430, & 440 chained for use with a Web service application 300.

After the smart nodes 302, 304, 306, and 308 and Web services 410, 420, 430, & 440 have been integrated, users can run the chaining Web service application 300 so that the communication dimensions for interoperability are automatically supplied for each Web service 410, 420, 430, & 440 by the smart nodes 302, 304, 306, and 308. Moreover, the specified functional specified in the smart nodes 302, 304, 306, and 308 will also be supplied automatically by one or more of the chained Web services 410, 420, 430, & 440 if one of those services becomes dysfunctional.

Note that, in an embodiment, the process describe above may be applied so that a smart node or set of smart nodes can be programmed to provide communications dimensions and functionality for multiple Web service applications, not just for one Web service application.

Example of Dynamic Orchestration

FIG. 4 and FIG. 5 illustrate how smart nodes can dynamically orchestrate the processes of a Web service application, based on the event context of that application. FIG. 4 shows an operating environment in an embodiment where smart nodes chained in an application have been set up in association with multiple Web-service endpoints (EP) for claims filing.

Smart node 1 302 is programmed to be associated with EP 1 702, which receives messages, such as patient claims from a clinic at client computer 1 150.

Smart node 2 304 is programmed to be associated with EP 4 708, which transforms message formats.

Smart node 3 306 is programmed to be associated with EP 7 714, which validates claim files.

Smart node 4 308 is programmed to be associated with EP 10 720, which sends files to a payer at client computer 2 170.

In a typical scenario, shown in FIG. 4A, the system carries out the following steps:

-   Step 1—The provider at client computer 1 150 sends a patient claim     to interface logic 600 at server 1 100. -   Step 2—The interface logic 600 relays the claim to smart node 1 302. -   Step 3—Smart node 1 302 employs EP 1 702 to receive the claim file. -   Step 4—Smart node 1 302 relays the claim file to smart node 2 304. -   Step 5—Smart node 2 304 employs EP 4 708 to transform the message     format of the claim file. -   Step 6—Smart node 2 304 sends the claim file to smart node 3 306. -   Step 7—Smart node 3 360 employs EP 7 714 to validate the claim file. -   Step 8—Smart node 3 306 sends the claim file to smart node 4 308. -   Step 9—Smart node 4 308 employs EP 7 720 to send the claim file to     the payer at client computer 2 170. -   Step 10—EP 7 720 sends the claim file to the payer at client     computer 2 170.

Returning to FIG. 4, note that each smart node is also associated with additional Web-service endpoints that may have other functionality, include backup functionality. For example, smart node 3 306 is programmed to be associated with EP 9 718, which transforms message formats. Smart node 3 306 can thus provide backup functionality for smart node 2 304.

FIG. 5 shows the same claim filing scenario listed above, but in a situation where this backup functionality for transforming message formats is very useful because smart node 2 304 has lost power and so is not functional. Because smart node 1 302 has been programmed sufficiently to respond dynamically to the event context, smart node 1 302 recognizes that smart node 2 304 is not functional and takes alternate step 4 to send the claim file to smart node 3 306. Because smart node 3 306 has also been programmed sufficiently to respond dynamically to the event context, smart node 3 306 knows a supply the missing transformation of the message format by employing EP 9 718 in alternate step 5 and then continuing to step 7 as before.

In the same way, all the smart nodes in a given chain may be programmed to provide all the backup functionality required by the application. In addition to the functionality described above, other embodiments can accommodate dynamic orchestration for any other useful aspect of the Web-service application, for example for security.

Computer System Overview

FIG. 6 is a block diagram that illustrates an example of a typical computer system 1400, well known to those skilled in the art, representing a server 100 on which embodiments of the present invention can be implemented. This computer system 1400 comprises a network interface 1402 that provides two-way communications through a wired or wireless link 142 to a wired or wireless communications network 130 that uses any applicable communications technology. For example, the network 130 can comprise a public telephone network, a wireless network, a local area network (LAN), and any known or not-yet-know applicable communications technologies, using correspondingly applicable links. The network 130 in turn provides communications with one or more host computers 150 and, through the Internet 1424, with one or more servers 103.

The network interface 1402 is attached to a bus 1406 or other means of communicating information. Also attached to the bus 1406 are the following:

-   -   a processor 1404 for processing information;     -   a storage device 1408, such as an optical disc, a         magneto-optical disc, or a magnet disc, for storing information         and instructions;     -   main memory 1410, which is a dynamic storage device such as a         random access memory (RAM) that stores information and         instructions to be carried out by processor 1404;     -   a bios 1412 or another form of static memory such as read only         memory (ROM), for storing static information and instructions to         be carried out by processor 1404;     -   a display 1414, such as a liquid crystal display (LDC) or         cathode ray tube (CRT) for displaying information to user of the         computer system 1400; and     -   an input device 1416, with numeric and alphanumeric keys for         communicating information and commands to processor 1404. In         another embodiment a mouse or other input devices can also be         used.

The computer system 1400 is used to implement the methods of the present invention in one embodiment. However, embodiments of the present invention are not limited to specific software and hardware configurations. Computer system 1400 can receive data comprising client application messages from computer 150 and server 103 used by client business, through an network 130 such as the Internet, an appropriate links 142, such as wired or wireless ones, and its network interface 1402. It can of course transmit data back to client business application over the same routes.

Computer system 1400 carries out the methods of the present invention when its processor 1404 processes instructions contained in its main memory 1410. Another computer-readable medium, such a its storage drive 1408, may read these instructions into main memory 1410 and may do so after receiving these instructions through network interface 1402. Processor 1404 further processes data according to instructions contained in its storage device 1408. Data is relayed to appropriate elements in computer system 1400 through its bus 1406. Instructions for computer system 1400 can also be given through its input device 1416 and display 1414.

“Computer-readable medium” refers to any medium that provides instructions to processor 1404, comprising volatile and/or non-volatile media. Volatile media comprise dynamic memory, such as main memory 1410. Non-volatile media comprise magnetic, magneto-optical, and optical discs, such as storage device 1408. Typical examples of widely used computer-readable media are floppy discs, hard discs, magnetic tape, CD-ROMs, punch cards, RAM, EPROMs, FLASH-EPROMs, memory cards, chips, and cartridges. Multiple computer-readable media may be used, known and not yet known, can be used, individually and in combinations, in different embodiments of the present invention.
